HODGKINS-DISEASE IN PATIENTS WITH HIV-INFECTION AND IN THE GENERAL-POPULATION - COMPARISON OF CLINICOPATHOLOGICAL FEATURES AND SURVIVAL

Background: Hodgkin's disease (HD) has been described in patients with HIV infection in association with unfavourable propostic factors. Similarly, HD in the older general population has a poorer prognosis than in younger patients. Patients and methods: With the aim of comparing the clinicopathological features and survival of HD in HIV-infected patients and in the general population, we analysed 176 patients with HD from 1986 to 1992. We divided the 84 HIV-negative patients into two groups: group A included patients less than 55 years old, group B patients of 55 years or older. This division was made in order to compare HD in HIV-infected patients with the less favourable group of patients with HD in the general population, i.e., older patients. Results: Patients of the older group and HIV-infected patients had a significantly lower frequency (31% and 21%, respectively) of nodular sclerosis subtype compared to the younger group (85%). Mixed cellularity (MC) is significantly more frequent both in the older group and in HIV-infected patients. Lymphocyte predominance is more frequent (16%) in older patients than in the other two groups. HIV-infected patients are more likely to show advanced stages, B symptoms, and extranodal involvement. Chemotherapy (CT) alone has been the most widely used (83%) treatment in HIV-infected patients, while CT plus radiotherapy (RT) has been mostly employed in the general population. Twelve (14%) HIV-infected patients did not receive any treatment. Complete remission was achieved in 51% of the cases in the HIV-infected patients, and around 90% of the cases in the general population. The estimated 4-year survival rate in the HIV-infected patients is much lower (33%) than in the other two groups (100% in group A, and 88% in group B). Conclusion: While MC is the most common histological subtype both in HIV-infected patients and in the older general population, HD in HIV-infected patients has a worse prognosis than in the older general population, not only because of underlying HIV infection, but also because of the more unfavourable clinicopathological features at presentation.
